Brakes and Traction Control: Description and Operation

This model is equipped with a vacuum assisted, hydraulic ABS. When the brake pedal is depressed, a piston is moved in the master cylinder. This piston forces hydraulic fluid into the brake system lines, applying pressure to the wheel cylinders. As the wheel cylinders extend, they clamp the disc brakes against a brake rotor and extend brake shoes against a brake drum. The primary brake system consists of the following components: a master cylinder, a vacuum booster, a proportioning valve, an ABS solenoid, brake lines, rear brake drums, and front disc brake assemblies. These items are all replaceable, or serviceable, with regular maintenance schedules. The parking brake system is a mechanical system used to hold the vehicle when parked.
